Application August 16, 1933, Serial No. 685,470 In Canada April 12,1933

1 Claim.

This invention relates to an electric light bulb guard and moreparticularly to a combined guard and light shade for electric lightbulbs which is an improvement over my prior Patent Number 1,893,409.

The primary object of the invention is the provision of a device of thischaracter wherein on the mounting thereof upon an electric light sockethaving a light bulb therein the same will serve to protect the bulb andalso will function as a shade for the light issued by the bulb, thedevice being adjustable to vary the shading of the light at the optionof the user of such device.

Another object of the invention is the provision of a device of thischaracter, wherein a shading shutter is movably supported in a novelmanner Within the guard of a semi-bulbous reflector so that onadjustment of the shutter the light rays from a bulb of the electrictype can be shut off or diminished accordingly to the requirement of theuser of the light, the device in its entirety being of novel form.

A further object of the invention is the provision of a device of thischaracter which constitutes an attachment or appliance for use with anelectric light bulb socket so that an electric bulb when fitted thereinor carried thereby will be protected or shielded and the light therefromcontrolled or regulated for shading purposes, the parts of the devicebeing assembled in a unique and novel manner.

A further object of the invention is the provision of a. device of thischaracter which is simple in construction, thoroughly reliable andefiicient in its purposes, neat in appearance, readily and easilymounted upon and removed from an electric bulb socket, strong, durable,easy of adjustment and fully protective for a bulb and also inexpensiveto manufacture.

With these and other objects in View, the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described in detail, illustrated in theaccompanying drawing, which disclosesthe preferred embodiment of theinvention, and pointed out in the claim hereunto appended.

In the accompanying drawing:-

Figure 1 is a side elevation of an electric light bulb socket showingthe device constructed in accordance with the invention applied thereto.

Figure 2 is a View similar to Figure 1 showing the device removed fromthe socket and the same in shifted position.

Figure 3 is a top plan view thereof.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawing.

Referring to the drawing in detail, A designates generally an electriclight bulb socket of any standard construction and B the light bulbfitted therein, this bulb being of the usual type. Adapted to be mountedupon and carried by the socket A is the guard constituting the presentinvention and hereinafter fully described.

The guard comprises a semi-bulbous shaped reflector or body member 5having an open side 6 through which issues the light from the bulb B.This reflector or body member 5 at its smaller end has a semi-circularband 1 bridging the open side 6 and this band with the companion portionof the member 5 constitutes a circular or annular track 8 for guiderollers 9 upon a semi-bulbous shaped shutter or closure 10 for the openside 6 of said reflector or member 5, the latter being rotatably pivotedat l l to the said reflector or member 5 while the rollers are'pivotedto the said shutter to project laterally onto the track and travel uponthe same on adjustment of the shutter. Superposed or spaced withrelation to the track 8 is an annular or circular retaining ring or bandl2 which holds the rollers engaged with the track 8. Uniting the ring orband l2 with the track 8 is a series of straps Band II respectively,these being joined with said track 8 in any suitable manner. v

The straps M are extended upwardly beyond the ring or band 12 and arejoined with a split ring-like clamp l6 which is adapted to embrace thesocket A and is made firm or fast thereon by a nut carrying bolt orfastener I! so that the guard will be mounted upon the socket A inproper position to permit the inclosing of the bulb B and thus guard andprotect the same.

In the use of the device when it is desired to shade the light issuingfrom the bulb B the shutter I I! is manually turned, thus reducing thesize of the open side 6 and in this fashion regulating the light fromthe bulb as should be clearly obvious. When the shutter I0 is completelyclosed it will obliterate the light rays from the bulb B and thus shutoff the light therefrom. v

The shutter I0 is fitted within the reflector or member 5 and its axisof movement is upon the pivot I i for the opening and closing actionthereof, while the rollers 9 guide such shutter when traveling upon thetrack 8 as will be obvious.

What is claimed is:

An electric lamp guard comprising a pair of semi-bulbous shaped members,one swingingly movable into the other and the other constituting astationary reflector, a band on the stationary reflector, the upper edgeof the band constituting a track, a roller carried by the swingingmember adapted to travel upon the track, a second band disposedvertically above said first mentioned band adapted to retain said rolleron the track, straps connecting said bands together,

disposed in the path of said roller to limit the movement thereof, apivot connecting said members remote from the bands and a clampintegrally formed with the upper ends of said straps adapted to embracethe electric lamp socket for securing the reflector thereon.
